This package provides factors out an opinionated selection of internal packages and functionality from the Go standard library. Currently this consists mostly of packages and testing code from within the Go tool implementation.

Included are the following:

• dirhash: calculate hashes over directory trees the same way that the Go tool does.

• goproxytest: a GOPROXY implementation designed for test use.

• gotooltest: Use the Go tool inside test scripts (see testscript below)

• imports: list of known architectures and OSs, and support for reading import import statements.

• modfile: read and write go.mod files while preserving formatting and comments.

• module: module paths and versions.

• par: do work in parallel.

• semver: semantic version parsing.

• testenv: information on the current testing environment.

• testscript: script-based testing based on txtar files

• txtar: simple text-based file archives for testing.

Go Windows Service wrapper compatible with GNU/Linux. Windows tests here.

GoLLRB is a Left-Leaning Red-Black (LLRB) implementation of 2-3 balanced binary search trees in Go Language.

This package provides a library for retrieving information on running processes and system utilization (CPU, memory, disks, network, sensors).

This package is toml parser and encoder for Go. The interface is similar to Go's standard library json and xml package. This package provides a command line interface (CLI) tool.

This package provides a Go implementation of the LevelDB key/value storage system.

Package multicodec exposes the multicodec table as Go constants.

containerd is a container runtime with an emphasis on simplicity, robustness, and portability. It is available as a daemon, which can manage the complete container lifecycle of its host system: image transfer and storage, container execution and supervision, low-level storage and network attachments, etc.

Package strcase is a package for converting strings into various word cases (e.g. snake_case, camelCase, kebab-case, etc).

This package provides a library for building interactive and accessible prompts on terminals supporting ANSI escape sequences.

Package pool contains helpers for pooling structures distinguishable by size.

This package implements a functionality of creating here-documents from raw strings.

Package lexer provides generating actionless scanners (lexeme recognizers) at run time.

This package provides a set of libraries that implementing low-level, kubernetes-independent packages supplementing the Go standard libs.

Package smetrics provides a bunch of algorithms for calculating the distance between strings. There are implementations for calculating the popular Levenshtein distance (aka Edit Distance or Wagner-Fischer), as well as the Jaro distance, the Jaro-Winkler distance, and more.

The uuid package generates and inspects UUIDs based on RFC 4122 and DCE 1.1: Authentication and Security Services. This package now leverages the github.com/google/uuid package (which is based off an earlier version of this package).

GoLog is a level-based logger written in Go.

This package provides ANSI colors for Golang. The package supports Printf/Sprintf etc.

This package provides an ANSI color package to output colorized or SGR defined output to the standard output.

rxhash is a Go library for creating a unique hash value for struct in Go, but data consistency.

Package optparse parses command line arguments very similarly to GNU getopt_long(). It supports long options and optional arguments, but does not permute arguments. It is intended as a replacement for Go's flag package.

This packages is fork of gopkg.in/yaml.v2 maintained by YAML organization.

shlex implements a simple lexer which splits input into tokens using shell-style rules for quoting and commenting.

go-cache is an in-memory key:value store/cache similar to Memcached that is suitable for applications running on a single machine. Its major advantage is that, being essentially a thread-safe map[string]interface with expiration times, it doesn't need to serialize or transmit its contents over the network.
